copy-store fails on a large graph where the max id > max integer with:

Copying from /x/graph.db to /y/graph.db ingoring rel-types [] ignoring properties [false] ignoring labels [] removing nodes with labels [] keep node ids false 
Exception in thread "main" java.lang.IllegalArgumentException: initial capacity cannot be less than 0

It looks like there is a cast from long to int on StoreCopy.java:219 causing the issue.

@gmann11 where do you see this cast? Can't see it? There is only one cast to int for a percentage output.

Which version are you looking at?

I pushed a fix to the 3.5 branch, could you try to build and use that?
